The Cordillera Huayhuash Mountains are extremely remote and extremely beautiful. To the south of the famous Cordillera Blanca, they form a separate mountain range that encompasses six peaks, including Peru’s second-highest mountain, Yerupaja Grande, 6,634 m. With numerous lagoon and glacial lakes dotted around their snow-covered icy peaks, they create a breathtaking and rewarding backdrop for this demanding trek that follows tiny mountain pass trails, into verdant valleys and offers unparalleled views of these mighty ice-covered giants in the peace and tranquility of the Andes.

Upon arrival, and after acclimatizing around Hatunmachay, switchback bends lead over mountain passes and the trail follows ancient Inca routes to Queropalca. Here, further acclimatization takes place by hiking to over 4,000 m carrying a light backpack, to ensure the best possible preparation for the altitude to be reached in the coming days. The first section into the Cordillera Huayhuash from Queropalca is technically straightforward, but the altitude and long days makes challenging. But wide-reaching views, green lagoons, hot springs, mountain lakes in which the surrounding peaks are reflected, breathtaking mountain passes and looking out over the ‘Matterhorn of the Andes’ are a just reward for the effort.

The 5,020-meter-high Cuyoc Pass marks the trek’s highest point, after which it’s downhill to Cutatambo below Siula Grande, a picturesque mountain, and the site of Joe Simpson’s ‘Touching the Void’ epic. Following the river upstream the trek takes you through landscapes of flowering cacti and waterfalls, which you would not expect at such altitudes. Continuing to Camp Gashpopampa at 4,600 m, you can spend the night here before an optional (and in the company of a mountain guide) ascent of the glaciated peak of Diablo Mudo, 5,350 m, with its 360-degree panorama that will remain etched in your heart.

Arriving at the end of the trek in Llamac, there’s no doubt that the Cordillera Huayhuash is one of the best hikes in the world. Both the natural environment here, and the encounters with local shepherds are experiences you’ll never forget. To make this strenuous trek a little less demanding, organize a support team locally or book through a provider who will arrange luggage transfers and more creature comforts.
